3D cutaway diagram of the human heart, showing internal chambers (left and right atria, left and right ventricles), valves (mitral, tricuspid, aortic, pulmonary), major vessels (aorta, pulmonary artery, vena cava), myocardium wall thickness, chordae tendineae, and septum. Medical illustration style, detailed anatomical labels, cross-section view revealing interior structure, realistic rendering with depth and shading.

3D cutaway anatomical illustration of the human hand, cross-section revealing internal structures with detailed labels: bones (carpals, metacarpals, phalanges - proximal, middle, distal), tendons (flexor digitorum profundus, flexor digitorum superficialis, extensor tendons), muscles (thenar, hypothenar, interossei, lumbricals), nerves (median nerve, ulnar nerve, radial nerve branches), arteries (radial artery, ulnar artery, palmar arches, digital arteries), ligaments (collateral ligaments, volar plate), synovial sheaths, skin layers. Medical textbook illustration style, clean white background, precise anatomical labels with leader lines, high detail 3D rendering with transparent skin layer showing interior structures.

3D cutaway anatomical illustration of the human hand showing internal structures with detailed labels. Cross-section reveals: bones (carpals, metacarpals, proximal/middle/distal phalanges), flexor and extensor tendons, thenar and hypothenar muscles, interossei and lumbrical muscles, median nerve, ulnar nerve, radial and ulnar arteries, palmar arterial arches, digital arteries, synovial sheaths, collateral ligaments, and skin layers. Medical textbook illustration style, precise label lines pointing to each structure, 3D rendering with semi-transparent skin revealing interior anatomy, white background, high resolution.

Anatomical medical poster of hand nerve pathways. Shows both palmar and dorsal views of the hand with clearly illustrated nerve distributions. Median nerve highlighted in yellow covering the thenar eminence and lateral 3.5 fingers, ulnar nerve in blue covering hypothenar region and medial 1.5 fingers, radial nerve in green covering dorsal lateral hand. Includes: carpal tunnel cross-section inset, nerve branch labels with leader lines, sensory distribution color map, motor branch annotations for thenar muscles and interossei, recurrent branch of median nerve, deep branch of ulnar nerve.
